You Do NOT Talk About Building Science Fight Club

Building science is not an objective subject to be discussed in a rational, calm way, always coming to the same conclusions. Yes, it's based on principles of physics that were settled long ago, but buildings are complex. They intermingle structure, HVAC, plumbing, an electrical system, materials for controlling heat, air, and moisture, and more.

Does heat rise? Or should we never say that because the second law of thermodynamics says that heat responds only to temperature differences, moving from warmer to cooler?

I'm glad to know someone else knows there are ways to cut residential electrical use without building science. I know how to save 7-25% for about $600-$1300 in 30 minutes. I tell people expect 8% and consider the rest as a blessing. Unfortunately, it's not windows, insulation, air sealing, duct sealing, or better heating & cooling performance, so know one takes me up on it. What does an electrical engineer anyway?

Allison, I always enjoy your articles, but I often do get a bigger kick out of the comment section. Between here and Home Energy Pros, you would almost expect there is some secret ring somewhere that energy nerds get into to duke it out. Now THAT is a Fight Club I would pay to see.

Ted, I'd like to finish your list for you: #4 - This ICF foundation has an effective "R" value of 50+ #3 - This ceramic paint has an equivalent "R" value of (100..500?) and you can find proof on the NASA website #2 - Vapor barriers always go on the inside wall BY CODE #1 - My favorite: Solar energy doesn't really work because the sun only shines 8 hours a day... (Actual statement from an energy "expert" at a seminar. Ahh, WHAT?)
